Changing batteries
– The bosotherm diagnostic is operated by two LR03 (AAA)
alkaline batteries. Please replace the old batteries with new
ones when the battery symbol blinks.
– Open the battery compartment cover and remove the batter-
ies from the battery compartment. Insert new LR03 batteries
and take note of the symbols for the poles in the battery
compartment: The (+) pole must correspond with the "+"
symbol and the (-) pole with the "-" symbol. Close the battery
compartment again after inserting the batteries.
– Saved temperature measurements are retained during a bat-
tery change.
– Avoid using new and old batteries from different manufac-
turers.
– Do not leave old batteries in the bosotherm diagnostic device.
This can cause the batteries to leak and can damage the
device.
Regular Checks on the Accuracy
Regular checks on the accuracy of the measurement system
